Finally the 5D III is out there and some are already using it. I have downloaded the part of the user manual dedicated to the new AF system, and while I suspect a little time reading and some hands on when the camera arrives will get me by, I'm sure that others will be more at home with it and able to share their experience.
What this thread will NOT be about, please, is to rubbish this or any other camera's AF or whatever...there are plenty of threads where that can happen.
So...to start I would like to ask the question...is anyone as yet comfortable with the Zone focussing system, and when do you use it?
And is there any advantage in using back button focus or does it tend to nullify the advantages of the new AF system?
